A nurse is assessing a newborn's head after a vaginal delivery. The nurse notes a soft, edematous area that crosses suture lines on the scalp. The parents ask how this differs from a cephalohematoma. Which of the following statements is correct?

Both caput succedaneum and cephalohematoma are superficial scalp swellings that are visible at birth, can cross suture lines, and generally resolve spontaneously within a few hours to a few days without any risk of complications.

Caput succedaneum is a collection of blood beneath the periosteum that is limited to a single cranial bone, does not cross suture lines, and may take several weeks to resolve, while cephalohematoma is a superficial scalp swelling caused by pressure during delivery that crosses suture lines and resolves within days

Caput succedaneum is usually firm and may be associated with bruising or ecchymosis of the scalp that develops within 24-48 hours after birth, while cephalohematoma is a soft, fluid-filled swelling of the scalp that crosses suture lines and resolves within a few days.

Caput succedaneum crosses suture lines and usually resolves within a few days without intervention, while cephalohematoma is a subperiosteal hemorrhage confined to one cranial bone that may take weeks to months to resolve and can slightly increase the risk of hyperbilirubinemia.
